DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1As shown, a contact lens curing production line includes a circulating transport line equipped with an upper transport track 2, a lower transport track 3 and a transfer device 7, and the transfer device 7 is configured to transfer the mold 100 transferred by the upper transport track 2 to the lower transport track 3 or transfer the mold 100 transferred by the lower transport track 3 to the upper transport track 2. The curing production line also includes a curing box 4 with a liftable curing plate 402 inside, and a curing light board adapted to the mold 100 is installed on the curing plate 402. Through the circulating transport line formed by the upper transport track 2, the lower transport track 3 and the transfer device 7, the mold 100 loaded with the workpiece is transported to the curing box 4 for curing operation, and the empty mold 100 after the curing is completed and the workpiece is taken away is transported back to the starting position, so as to realize the cyclic transmission of the mold 100.

[0027] like Figure 2 , Figure 3 As shown, the upper transfer track 2 and the lower transfer track 3 are arranged opposite to each other in the upper transfer track 2. The transfer station 1 201, the curing station 202 and the transfer station 2 203 are arranged in sequence on the upper transfer track 2. The curing box 4 is mounted on the curing station 202 and covers the entire curing station 202.

[0028] The upper transmission track 2 and the lower transmission track 3 are equipped with blocking cylinders 9 that are raised or lowered by the detection part 6; specifically, a blocking cylinder 9 is arranged between the transmission station 1 201 and the curing station 202, a blocking cylinder 9 is arranged between the curing station 202 and the transmission station 2 203, a blocking cylinder 9 is arranged between the transmission station 2 203 and the transfer device 7, and a blocking cylinder 9 is arranged between the tail end of the lower transmission track 3 and the transfer device 7; the head end and tail end of the transmission station 1 201, the head end and tail end of the transmission station 2 203, and the head end and tail end of the lower transmission track 3 are all equipped with detection parts 6. In this embodiment, the detection part 6 is a photoelectric sensor, which is used to detect whether the mold 100 is in place or to count the molds 100 transported on the transmission line, and timely trigger the blocking cylinder 9 to perform corresponding actions.

[0029] For example: the curing station 202 can cover 8 molds 100, and can be used for curing operations on 8 molds 100 loaded with workpieces. The detection part 6 on the transfer station 201 counts when the mold 100 is transferred. When there are 8 molds 100 on the curing station 202, the blocking cylinder 9 on the transfer station 201 and the curing station 202 extends to block the transfer station 201 from transferring the mold 100 to the curing station 202, and also blocks the mold 100 in the curing station 202 from being transferred to the transfer station 203.

[0030] At this time, the curing operation is carried out in the curing box 4, and the curing time can be set. In this embodiment, the curing time is set to 7 minutes. After the curing is completed, the curing light board is turned off, and the blocking cylinder 9 on the transfer station 201 and the curing station 202 is retracted. The transfer station 201 and the curing station 202 are normally transferred, and the next round of curing operations of 8 molds 100 are carried out.

[0031] After the curing station 202 transfers all the cured workpieces, the mold 100 located at the head end of the transfer direction will hit the blocking cylinder 9 on the transfer station 203. At this time, the detection part 6 gives a signal, indicating that the interior of the curing box 4 is empty and is ready to transport the mold 100 to the transfer device 7. At this time, the external robot (not shown in the figure) takes away the cured workpiece, leaving the empty mold 100.

[0032] It should be noted that two adjacent blocking cylinders 9 are provided on the transfer station 203. The two blocking cylinders 9 respectively block the two adjacent molds 100 and wait for the robot to remove the workpiece on the mold 100 between the two blocking cylinders 9, and then retract the blocking cylinder 9 close to the transfer device 7. At this time, the unloaded mold 100 is transferred from the transfer station 203 to the transfer device 7, and clamped and fixed by the clamping mechanism 8, and then the unloaded mold 100 is transferred to the lower transfer track 3 by relying on the lifting cylinder 701. In order to facilitate the transfer of the mold 100 from the lower transfer track 3 to the upper transfer track 2 through the transfer device 7, two adjacent blocking cylinders 9 are also provided at the tail end of the lower transfer track 3.

[0033] In addition, when the unloaded mold 100 is transferred from the transfer station 203 to the transfer device 7 and clamped and fixed by the clamping mechanism 8 for transfer, the next mold 100 is transferred between the two blocking cylinders 9 and waits for the robot to pick up the material, which can realize the synchronization of material picking and transfer processes and improve efficiency.

[0034] like Figure 5 As shown, the transfer device 7 includes a lifting platform 703 that can move up and down. The lifting platform 703 is driven by a lifting cylinder 701 to move up and down. The lifting platform 703 is slidably connected to a slide rod 702. The lifting cylinder 701 and the slide rod 702 are both fixed on the frame 1. The slide rod 702 is used to improve the stability of the movement of the lifting platform 703.

[0035] In addition, please refer to Figure 6The lifting platform 703 is internally provided with a driving member 704 and a relatively distributed rotating rod 705 and a driven rod 706. The driving member 704 drives the rotating rod 705 to rotate and drives the driven rod 706 to rotate. The rotating rod 705 and the driven rod 706 cooperate to drive the belt to move, thereby driving the mold 100 to move. The driving member 704 is a motor. Gears are installed on the driving end of the motor and the rotating rod 705. A chain (not shown in the figure) is sleeved on the gear. Through the cooperation of the motor, the gear and the chain, the motor drives the rotating rod 705 to rotate, and then drives the driven rod 706 to rotate through the belt, so that the belt can bear the mold 100 and drive the mold 100 to move.

[0036] The lifting platform 703 is driven up and down by the lifting cylinder 701, so that the lifting platform 703 can transfer the mold 100 transmitted by the upper transmission track 2 to the lower transmission track 3 or transfer the mold 100 transmitted by the lower transmission track 3 to the upper transmission track 2.

[0037] like Figure 5 , Figure 6 As shown, a clamping mechanism 8 is installed on the lifting platform 703, and the clamping mechanism 8 is used to clamp and fix the mold 100 transmitted to the transfer device 7. A proximity sensor 707 is installed on the lifting platform 703, and the proximity sensor 707 is configured to detect whether the mold 100 is in place. When the proximity sensor 707 detects that the mold 100 is in place, the clamping mechanism 8 is triggered to act. Specifically, the clamping mechanism 8 includes two mirror-image clamping claws 803 adapted to the mold 100, and the clamping claws 803 are connected to the telescopic cylinder 801 through the mounting plate 802, and the telescopic cylinder 801 is installed on the frame 1. Both ends of the telescopic cylinder 801 are provided with driving ends, and the clamping claws 803 are driven to move by the telescopic cylinder 801. When the transfer device 7 drives the mold 100 to move up and down, the mold 100 is clamped to prevent the mold 100 from shifting. When the transfer device 7 drives the mold 100 to move horizontally, the mold 100 is released, so that the mold 100 can be normally transferred to the upper transmission track 2 or the lower transmission track 3.

[0038] In addition, if Figure 5 As shown, auxiliary rollers 204 for assisting the movement of the mold 100 are installed at the head and tail ends of the upper transmission track 2 near the transfer device 7. The ball rollers 204 are used to receive the mold 100 between the transfer device 7 and the upper transmission track 2 or between the transfer device 7 and the lower transmission track 3 to improve the stability of the lateral movement of the mold 100.

[0039] Please focus on Figure 4The curing box 4 includes a main frame 401, on which a screw 403 driven by a motor is arranged, and a nut 405 is arranged on the screw 403. The curing plate 402 is mounted on a lifting plate, and the lifting plate is sleeved with the screw 403, and the lifting plate is located above the nut 405. The rotation of the screw 403 can drive the nut 405 to move on the screw 403. When the nut 405 moves upward, the lifting plate can be lifted to increase the distance between the curing plate 402 and the mold 100. When the nut 405 moves downward, the lifting plate falls by its own weight, which can shorten the distance between the curing plate 402 and the mold 100, thereby realizing the adjustment of the position of the curing plate 402.

[0040] In addition, the main frame 401 is also provided with a guide rod 404 , the lifting plate is sleeved with the guide rod 404 , and the curing box 4 is also provided with an observation window 5 .
